IQ (HE/2 RTEQED- TEQMEIRE GET/IEABTY, SF HARTFURD, CQHNEUTICUT, A OGRIPDRATEQN' @F .EJY JIIIVEEtY AiPP/ My invention relates to apparatus for delivering mold charges of molten glass to i the molds of glassware shaping machines, and it relates more particularly to mechanism adapted to deliver mold charges from one glass feeder to the molds of, u plurality of shaping machines. I v

@no object of my invention is to providesuch glass-delivering apparatus with -im proved mechanism for operating a plurality of delivery devices, hereinafter called scoop blocks, in a desired sequence to receive mold charges of molten glass from the discharge outlet of an automatic feeder and to deliver the charges in proper order to designated mold: of a plurality of shaping machines. This hject is accomplished by locating the scoop docks about the feeder-outlet in any conw ent manner and mounti'n each scoop 2o block upon e movable supportw ich may he operated by a fluid-pressure mechanism to move the scoop block into and out of glassreceiving position. a

More specifically, my invention contemplates mounting each scoop block upon the piston rod of a fluid-pressure cylinder which is positioned relative to the feeder so that the piston moves and guides the attached scoop block into alignment with the feeder 80 outlet and into alignment with e trough section associated with one of the shaping machines. The arrangement and timing of the scoop blocks is such that, after'one scoop husfreceivedand delivered a charge, it is sponding trough andaway from the feeder outlet in order to permit another scoop to be brought into glass-receiving position 'be neath the feeder outlet. and into alignment with another trough section to deliver a mold charge to another shaping machine. In this way mold charges may be delivered to the molds of the several shaping machines in any desired sequence.

Another object of this invention is to provide an improved delivery apparatus which shall he pneumatically operated in synchronism with the several shaping'machines and controlled by timing mechanism connected to the feeder mechanism.

Fig. 7 is a front elevational view of the apparatus illustrated in Fig. 6.

Referring toFig. l of the drawings, there is illustrated a glass delivery apparatus emhodying the present invention, in which two 7 scoop blocks 10 and 11 are arranged to be moved laterally into and out of alignment with two inclined stationary delivery troughs 12 and 13 which are positioned to de- .liver mold charges to two shaping machines.

Mold charges ere delivered to the scoops by -*means of any suitable glass'feeder, such as that indicated by the numeral 14, Fig. 2, in-which a forehearth 15, connected to a glass meltingtank, not shown, is rovided with a discharge outlet 16 and in which the discharge of glass from the outlet is regulated by means ofa plunger 17 to form mold charges of the desired size and shape which are severed by shears 18. The feeder above described is substantially of the type illustrated and described in a patent to Karl E. Peiler, No. 1,7 60,254, dated May 27, $30,126 which reference may be made for a morev detailed description of these charge-forming instrumenteiities, which formno part of the pres ent invention.

The shaping machines may be of any" de sired type, and for the purpose of illustrating the invention, two rotary machines are indicated by the numerals 20 ami 21 and may be of the intennittently-opereted type, As shown, each of the machines is provide& with a plurality of molds 22 ancl 23, respectively, to which mold charges are sup lied by the stationary troughs 12 and 131 leading from the glass feeder. The molds may he provided with any suitable means for deflecting the mold charges from the troughs into the molcls as they are presenteri to the troughs, 7

As heretofore pointed out, the delivery scoops are srrangeol about the feecler outlet on movable si pports and. the support for esch scoop comprises an inclepentiently-operetai fluid pressure cylinder. As shown in the iilustretecl embodiment of the invention, the scoop'blocks 1G ii are supported on the piston rods of operating cylinders 24 one 25, respectiveiy. The scoop hloch Ill, for example, is fixecliy monnteclnpon s giston ro'ci 26 extending through the supporting" cylinder 25 which may be mounted on the feeder frame, The scoop block 11 secured to the piston rod in soy suitable manner, as for example, by a clamp rnechsnisin es indicated 27.

The relative po sitions of these circumferential ports are shown in Fiend i a 5 H By providing separate valve rotor mem: bers forindependently;controlling the admission of fluid pressure to the glass delivery' mechanism and to the shaping-machine control mechanism, i am enabled to regulate the instant at which the delivery scoops are. presented'to the feeder outlet to receive a mold charge. this period ofoperation is established, the rotor section 44' for controlling theinstant at which the shaping machine is tripped ofif or otherwise. actuated, may be angularly adjusted relative to the previously adjusted section 43, so as to cause chines llt iscontemplated the shapingmachine to be actuated at the proper intervals to receive its charges from the delivery mechanism There being several pneumaticallyoperated scoop blocks, it is essential that thetime'r cause a delivery scoop to he moved into position beneath the feeder outlet to receives mold charge when severed by the shearmechanism and that at substantially the some instant a mold on the shaping machine be pi'isitionedv relative to an associated trough. to receive the charge It may happen that tie period of delivcny oi successive mold charges is not equal and in such cases it is necessary to timeeach new chine to its corresponding delivery mecha nism. i A. modification of the inventionis illustrated Figs 6 and Z in which four piston operated. scoop blocks 61 692 t3 disposed about a feeder" outlet indicated at 64; this embodiment oi the inventiom two iiuidpressure cylinders, carrying the scoop blocks diland 6-3 are spaced laterally from the feeder outlet and two cylinders for operating the scoop hloclss Gi are located helow e outlet and. incliueci'ijrom the vertical pou ticu. cylinders are arrai'igcd to periodicei T move the scoops to position beneatli thefeeder outlet andinto aliginnent with' cooperatie f sistionary troughs @i 66 6'6 and thus del ver mold charges the severe: s 21g cylinders shall be timed to operate in any desired sequence toreceive mold charges from the feeder, according to the principles de scribed above in connection with the feeding of two machines.
